I have a HP T5710 Thinclient. It came out of an AT&T kiosk. I need to know how to modify the embedded XP so that it doesn't boot roght to the AT&T software. F8 at windows boot does nothing, as well as CTRL+ALT+DEL and Windows key+D does nothing. Any ideas? I basically want to wipe any of the AT&T kiosk stuff off and use it as an internet client.
